    when you get a Cursor returned from the database you should do an moveToFirst(); before trying to get data from it. try this

    void populateFrom(Cursor c, NoteHelper helper) {
    if (!c.moveToFirst()) return; //if no data dont do anything
    b1.setText(helper.getNote(c));
        c.moveToNext();
    b2.setText(helper.getNote(c));
    c.moveToNext();
    b3.setText(helper.getNote(c));
}
